Frequently Asked Questions
Q: Why do I need a water pressure reducing valve on my RV?
A: Campground water pressure often exceeds 100 PSI, while RV plumbing systems are designed for 40-60 PSI maximum. This valve protects your water heater, pipes, and fixtures from burst lines and premature failure caused by excessive pressure.
Q: Where does this valve install on my RV?
A: This reducing valve installs inline between your fresh water hose and the RV's city water inlet connection. It's typically installed at the point where you connect to campground water supply.
Q: Is 12 PSI enough water pressure for my RV?
A: Yes, 12 PSI provides adequate flow for most RV fixtures while protecting your plumbing system. Many RVers prefer lower pressure settings (10-15 PSI) to extend the life of their water system components.
Q: Can this valve be used with both hot and cold water lines?
A: This valve is designed for cold water inlet regulation. It installs before water enters your RV system, protecting both hot and cold water lines downstream from excessive pressure.
